METAL WINDOW FRAME AND SASHES.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed February 10, 1916. Serial No. 77,364.

To all whom it may concern:

Be it known that L'Hannr E. GAMrBnLL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Metal /Vindow Frames and Sashes, of which the following is a specification.

The invention relates to metal windowframes and sashes, and consists in the means more particularly hereinafter set forth, wherebythe entrance of dust and air past the joints between sashes and frame s pre whereby the construction is simplified and cheapened.

In the accompanying drawings-Figure 1 is a vertical section of ,my window-frame and sash on the line 1, l of Fig. 6. Fig. 2 is a vertical section on the line 2, 2 of Fig. 6, showing -sashes 10, 11 in normal position. Fig. 3 is a partialsection similar to Fig. 2, but showing the lower sash 1O raised to the top of the frame, and the upper sash 11 lowered to the bottom of the frame. Fig. 4 is a section on the line 4, 4 of Fig. 2. Fig. 5 is a section on the line 5, 5 of Fig. 3. Fig. 6 is a section on the line 6, 6 of Fig. 1 the sash and members S, T' being omitted for. the sake of clearness. Fig. 7 is a vertical enlarged section through the sill flange 16 and bar 21.

Similar letters and numbers of reference indicate like parts.

The window-frame comprises a lintel box A, sill B and hollow jambs, generally indicated at C, interposed between lintel and sill, said parts being connected by tie-rods D. The jambs on each side are alike, so that the description of one applies to both. Each jamb is formed of a metal plate E, bent at right angles at its end portions F and G, Fig. 4, the portion F being again bent at right angles to form a flange H. To said flange is seemed a plate I by screws Y passing through slots in said plate near one edge thereof; the opposite edge K of plate I is curved inwardly. To the portion G is welded a plate L, having a portion J bent at right angles, the edge M of said portion being curved over to correspond to the curved over edge K of plate I. The parts I and J are in the same plane, and are separated by a space between the curved over edges K and M. By reason of this construction there are formed within the jamb two vertical coxnpartments,

in which the sash counterweights 8 and 9 are disposed.

On the inner side of the jamb is bolted the flange of a partition N, separating said weight compartments, to which partition is secured the middle arm of a- T-shaped bar 0. The outer face of bar 0 is flush with theouter surfaces of parts I and J, but between the curved over edges K and M and the adj acent edges of bar 0 narrow vertical slots are left. Through one of these slots passes a plate P, extending laterally from the lower sash 10, and through the other of said slots passes a similar plate Q, extending laterally from the upper sash 11. There are similar plates extending from the opposite sides of said sashes into similar slots in the opposite jamb, so that when said sashes are raised or lowered, said laterally extending plates are guided by said slots. To each laterally extending plate is secured a plate R by bolts passing through slots in said plate R, and each of these extension plates may, there-- fore, be adjusted on its supporting plate so that the outer edge of the extension plate may be brought into proximity to the inner surface of the portion E of the amb, Figs. 4 and 5.

Upon one side of the lower half of parti tion N are bolted a number of leaf springs S, Fig. 2, which at their outer ends carry a vertical angle-strip T, Fig. 2. This strip is disposed below the'upper sash l1, and its flange is beveled at its upper end, as shown at U in Fig. 2. When the upper sash is in raised position, the vertical edge of the flange of strip T lies against the curved over edge M of jamb plate J, Figs. 2 and 4. When the upper sash 11 ismoved downwardly, it acts upon the beveled upper end U to push the strip T outwardly against the resilience of springs S, so that the sash 11 enters between said strip T and the jamb plate edge M. The strip T is held closely against the side rail of the sash 11 by the springs S, and the joint between said parts is thus kept closed. A similar vertical angle-strip V is carried by leaf springs W bolted to the opposite side of the upper half of partition N. This strip is disposed above the lower sash 10, and its flange is beveled at its lower edge X, as shown in Fig. 2. When the lower sash is in closed position, the vertical edge of the flange'of strip V lies against the curved over edge K of jamb plate 1, Figs. Zand 4. When the lower sash 10 is moved upwardly, it acts upon the beveled lower and X to push the strip V outwardly against the resilience of springs IV, so that the sash 10 enters between said strip and the jamb plate edge K. The strip V is held closely against the side rail of the sash 10 by the springs W, and the joint between said parts is thus held closed. When the sashes are in normal closed position, the strips T and V close the portions of the jamb slots not occupied by the projecting plates P, Q of said sashes. I

The sashes are, suspended by sprocket chains 12 passinghver sprocket pulleys 13, the pair of pulleys associated with each sash being mounted on one. shaft 14, and the two pulley shafts being journaled in bearings (not shown) in the lintel. A. V

The lower rail of the lower sash comprises a plate of sheet metal, formed as shown in Fig. 1, having an inwardly struck up rib 15. When the sash is closed, said rib comes over the upwardly projecting flange 1 Fig. 7, on the sill B. The lower portion 17 of said plate lies against the outer face of flange 16. The rib 15 is secured to a rail plate 18 which extends downwardly over the inner face of said flange 16, and its upper portion 19 is inwardly flanged to be grasped by the operator in raising or lowering the sash. On the sill B is removably secured by screws 20 a slotted bar 21, Fig. 7, between which bar and the sill flange 16 the plate 18 enters.

The hollow jambs each comprise but three plates namely, the plate E, the adjustable plate I and the plate L. The plate E is designed to be formed by a plate-bending machine and to contain the maximum number of bends (three) which such machine is capable of effectively making.

The partition N and the springs S and W are flexible. Consequently when the adjust able plate I is set out to diminish the space between the curved over edges M, K of plate I and plate L, pressure on strip T will be transmitted through springs S, W and partition N to the other strip V, so that the joints between both strips T, V and edges K, M or between said strips and the rails of sashes 10, 11 will be tightened simultaneously. When the strip flanges press on said sash rails, these, in turn, are, of course, set outwardly to press on the turned over edges K, M. This arrangement is practically dust and weather-proof.

I claim:
